I thought that making a broken five-prime would be better than
switching points, but XG violently disagrees. Major modifications
are required to sway XG from switching points (see variants).

I'll enter on the 23 and then make the nine point. This builds a broken
five prime and it seems like priming is the most likely game plan that wins.
